Trying to find a 600V (575v-600v) coil
ABB brand
SK 824 101
Looks like this one, just in a 600V.
I’m about to give up..
Hoping someone here knows where one is located.

The last two digits are the coil voltage. See where the part number ends in “DB”? Change that to “AV” and search, that is the designation for a 600V coil for that contactor

Thanks! That was what is was needing, the voltage code.

I thought there was a used breaker company in Georgia that had old used parts.

I did what Jraef suggested, plugged in AV on the end and found these used coils on ebay:

https://www.ebay.com/itm/1742496746...cWeb&brand=ABB&_trksid=p2563228.c101113.m2108



I am confused. I always thought that the 500-600V rating had to do with the voltage class that the contacts were interrupting and separate from the coil voltage that pulls in the contactor/ relay. I have never seen a coil rated in the 500-600V range. I thought the electrical standards did not allow that.
Another approach would be to try searching for the contactor/ relay that this coil came from.

Are trying to find the coil for an EH145 contactor?
If so, there's some info I found below about coils for it.

Here are some vendors that might have the KH145-6 coil for 600V, but you'd have to check on that:

This link shows that the 24VDC coil in your picture is designated by ABB as a KH145 type:

I think the SK828100 coils are for larger contactors than the SK824100 ones based on the dimensions and weights shown in the following datasheets. You might ignore the picture in them, because it appears to be the same one in all of the EF series coil datasheets.

As ATSman suggested, it's important to know what specific ABB contactor that the coil is for.
